Thats fine and does not have to be edited. The automatic network configuration is disabled by default, so these values are not used until you enabbled automatic network configuration and this is supported only on debian.

I noticed this myself. I would suggest for usability that it should either try to detect what the system already has, or makes more likely defaults.

From the point of view of a new user, this looks like it just shows existing settings, and you'd save it to tune them. But if the user did so, it would be highly destructive to them (I could even imagine losing server access as a result of wrong settings here).
